Colouring mineral oil in a two phase product.
Good day. I have a two phase product, the top phase consists of mineral oil and few plant oils and the bottom phase glycerine, water, and a preservative with glycerine being the highest percentage in the phase. The brief is to make the oil phase a hazy/white colour. What can I use to colour the oil phase only, that will not sink down to the glycerine phase?

The only thing I can think of would be to use titanium dioxide or zinc oxide that comes predispersed in oil. Issue would be if they aren’t suspended properly, they might settle.
If im not mistaken, i think the issue with this is that most of the time haziness comes from something that’s insoluble, even particles, which causes light scattering.
